Abstract (en)

Provided is a photocatalytic coating in which the coating per se is hardly eroded even when a photocatalyst is excited and a coating surface having strong hydrophobic tendency can be formed. The photocatalytic coating is prepared by dispersing or dissolving at least a photocatalyst, a tetrafluoro-ethylene-based resin obtained by graft polymerization of a sulfonic acid, a compound containing metal ion having an ionic radius not less than an ionic radius of calcium and/or complex ion having an ionic radius not less than the ionic radius of calcium into a solvent. Further, hydroxide is used as the compound containing the metal ion or an electrically neutral surfactant is added to the photocatalytic coating.
